My boyfriend and I stayed at Piya's place from December 30the till January 5th. Piya's place is very small, but cozy. The living room is tiny, but the bedroom and especially bathroom is very good size. The bed is firm, clean and comfortable and the washroom is well lit and spacious. We really enjoyed having breakfast on the little balcony and having a small but very function kitchen was a great advantage. Piya also provided water, snacks and coffee which was very thoightful and helpful! We were checked in to the room by Piya's sister, who speaks a little English and is a sweetheart, very pleasant and helpful :)
The pool is absolutely amazing, very big and with a beautiful view of the Bangkok. Make sure to ask Piya for the pool cards as there is a security guard at the door asking to present the cards. The water in the pool is pretty chilly, but after running around all day in busy Bangkok coming home to take a dip at the pool is absolutely fantastic! There is also a washer and a dryer on the main level which we used once, it's 30-40 baht ($1.5 CAD) for one load of washing/drying, which is very convenient if you a traveling for an extended period of time in Thailand.
We loved the location. It's a bit away from downtown, but very close to BTS (sky train) so we did not have to take taxis to get around the city. Piece of advice - get a One Day Pass (140 baht = $6 CAD) so you can jump on and off the sky train as many times as you want. It is the most economical deal they have ;)
Also, there is 7/11 right across the building which is very convenient especially if you arrive on the late flight as we did (fyi there is a late arrival fee of 250 baht = $10 CAD as Piya's sister has to wait for you to get to the condo from the airport) so you can grab some snacks. To the left of the building there is a little market which sells amazing Street food, fruits and vegetables. Some of the street vendors change every few days so there is always a new selection of products. In our experience, restaurants in Bangkok are overpriced and it's really hard to find a good restaurants serving delicious food at reasonable prices, but street vendors never dissapoint! They cook delicious and very flavourful food, very fast and for very cheap prices. We ate lunch and dinner with Street vendors every day and never had any stomach issues, so don't be afraid and dig into the real Thai food ;)
Overall, we really enjoyed our stay at Piya's place. She was always quick to reply to my messages and answer any of my questions. She was very helpful and friendly. I would definitely recommend this place to other people :)
